fsx ifly 737 speed problem

hey(:, hope some one can help me with my little problems,
i have the ifly ngx for fsx, and i have a problem when i am climbing to my cruising altitude, the speed is getting up but when i get to the mach speed in FL250 and i putting the mach to 0.75 the mach index is staying at 0.54 and the gs staying at 330.
i have a friend with a ifly ngx and he doesnt have this problem, when he put the mach speed to 0.75 its going up to 0.75, and the gs is at 425. its showing that i am on the max speed near the red limit but it doesnt really show on the numbers that i am on that speed,
thanks for any help if you need that i will explain better i will try thanks!, and btw any one else has a problem with the texi lights? it sometimes not showing up, thanks again regards!;)

please help(:
